I was searching a way to modify the original phono-in entry (for connection of vynil disc player, with RIAA equalization) to a line-in entry (for connection of modern analog entries, eg. ipod, mp3player).
This service manual gave me the correct hints.
It contains very useful infos for repairing and modifing the hi-fi, such as disassembling instructions, block diagrams, schematic diagrams, PCB prints, replacement parts list.
Very good!
CPU (LSI201: MSM6387-13)
The CPU contains a sound data ROM and a DAC (Digital to Analog Convertor), and it provides a sound waveform in accordance with the pressed key and the selected tone. The following table shows the pin functions of LSI201. Pin No. 1, 2 3 4 5 6 7 8 9 10 11 ~ 18 19, 20 21 ~ 30 Terminal TEST1, TEST2 RESET AVDD OUT AGND GND COSI COSO VDD KI0 ~ KI7 KO11, KO10 KO9 ~ KO0 Out In In In In Out In In In In/ Out Function Not used. Connected to ground. Power ON reset terminal. When the power switch is turned on, the terminal receives a low level signal and the internal circuits of the LSI are initialized. +5 V sorce for the built-in DAC Sound waveform output Ground (0 V) source for the built-in DAC Ground (0 V) source 21.725 MHz clock pulse input Not used. +5 V source Input terminals from keys and switches Not used. Key and switch scan signal outputs
